1) Let's complete the square to solve x² -16x -8, step by step

x²-16x-8 =0 Dividing 16 by 2 we have 8, so let's make it (x-8)²

x² -16 =8

x²-2(8)x +64 = 8+64 To keep it balanced write 8² on the right side too

(x -8)² = 72 Leave the binomial on the left side

√(x-8)²=√72

x-8 =6√2 and x -8= -6√2

x_1=6√2+8

x_2 = -6√2+8

S ={6√2+8, -6√2+8)
